A quad copter is a multi rotor drone with 4 motors attached. Quadcopter stabilize its flight using electronic sensor and control system. There are two types of quad copters viz. 1- Plus configuration quad copter and 2- Cross configuration quad copter. In this tutorial, we will design a quad copter of X-shape. Both the shapes are stable but in forwa...
Frame: Frame is the basic structure of the drone on which all the component are mounted together. The frames should be rigid so that it minimizes the vibrations from the motor. It consists of a center plate to which the electronic components and the four arms are attached to the center plate. In the image given below, we can see frame of quad copte...
Brushless motor is 3 phase motor so it cannot be operated with DC power. ESC generates three frequency signals, with different but controllable phases continuously to keep the motor turning. It has a battery input and three phase output for the motor. We are using 30Amp ECSs here. In the image below, we can see how the ESC looks like. We are going ...
KK2.1.5 is a flight controller; the flight controller is also called the brain of the drone because with this all the operation of the drone is controlled. KK2.1.5 has ATMEL mega 664PA IC inbuilt inside it. It is 8-bit AVR RISC based microcontroller with 64k of memory. It has inbuilt accelerometer and gyroscope, 6050 MPU and auto level function. It...
The movement of the quad copter is controlled by varying the relative thrust of each of the 4 motor. Here, we are using quad copter of X shape. In this quad copter, the motor located on the same diagonal moves in the same direction either clock wise direction (CW) or counter clock wise direction (CCW). If we are going in a car then we can go front,...
As we can see in below block diagram, all the motors are connected with KK2.1.5 through ESCs. Accelerometer and Gyroscopes are shown outside the KK2.1.5 board but it is built inside the board itself. A receiver is connected directly with KK2.1.5 board. In the image given below, we have shown the block diagram of quad copter.
To fly the drone, we have only 4 types of input. These four inputs are controlled by giving more or less power to the motor. There are 4 motors here, motor 1 & 3 are rotating in CW direction and motor 2 & 4 are rotating in CCW direction. Ꞷ1, Ꞷ2, Ꞷ3, Ꞷ4 are the angular speed of motor 1 , motor 2, motor 3 & motor 4. l is the distance between diagonal...
Kk2.1.5 multi rotor LCD flight controller board is built on ATML644 PA. Right hand side of board has 8 outputs of which we will be using four only output to connect ESCs directly. We are going to use quad copter so we have used only four output pins. ESC’s Connections: Output pins have 3 pins in each row. Right most all pins are ground. All center ...
For setting up KK2.1.5 board, first keep the transmitter on and ensure that the receiver is bound to transmitter. There are four buttons at the bottom of the KK2.1.5 board S1, S2, S3 and S4. Using these buttons, we will interact with LCD display. Step-1First go to menu by pressing S4 then go to load motor layout then select quad copter X mode and s...
Very low P Gain: It is very hard to control the quad copter and quad copter lacks overall stability. Control inputs feel imprecise and slow when the craft responds. When quad copter will fly, it will be easy to over correct a command and craft will be jittery. Very High P & I Gain: Quad copter will suffer from side to side oscillation. Quad copter ...
Go to the "Receiver Test" menu and use the transmitter trims to set the Roll, Pitch and Yaw values to zero. Switch off Self Level. Set the I gain to zero for Roll, Pitch and Yaw. Hover the multicopter and move in one axis (Roll, Pitch or Yaw) and quickly centre the TX control stick.

Mar 15, 2014 · No further revisions are planned for either the kk2.0 or the kk2.1 (kk2.1.5) according to Steveis. With the kk2.1 I originally flash rev10 and have noticed obvious performance differences post reflashing to rev14.
